mac "newlines' in the sense that newlines from an MAC OS.
But the file is sent and received in Unix only..
So I assume that '\' is the escape character and 015 is the new line that we are replacing with nothing here..
Is it right..?

mac_ifoff
MAC_IFOFF(4) BSD Kernel Interfaces Manual MAC_IFOFF(4)
NAME
mac_ifoff -- interface silencing policy
SYNOPSIS
To compile the interface silencing policy into your kernel, place the following lines in your kernel configuration file:
options MAC
options MAC_IFOFF
Alternately, to load the interface silencing policy module at boot time, place the following line in your kernel configuration file:
options MAC
and in loader.conf(5):
mac_ifoff_load="YES"
DESCRIPTION
The mac_ifoff interface silencing module allows administrators to enable and disable incoming and outgoing data flow on system network inter-
faces via the sysctl(8) interface.
To disable network traffic over the loopback (lo(4)) interface, set the sysctl(8) OID security.mac.ifoff.lo_enabled to 0 (default 1).
To enable network traffic over other interfaces, set the sysctl(8) OID security.mac.ifoff.other_enabled to 1 (default 0).
To allow BPF traffic to be received, even while other traffic is disabled, set the sysctl(8) OID security.mac.ifoff.bpfrecv_enabled to 1
(default 0).

No labels are defined.

HISTORY
The mac_ifoff policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.
AUTHORS
This software was contributed to the FreeBSD Project by Network Associates Labs, the Security Research Division of Network Associates Inc.
under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.
BUGS
See mac(9) concerning appropriateness for production use. The TrustedBSD MAC Framework is considered experimental in FreeBSD.
While the MAC Framework design is intended to support the containment of the root user, not all attack channels are currently protected by
entry point checks. As such, MAC Framework policies should not be relied on, in isolation, to protect against a malicious privileged user.
